IT Services and Cybersecurity in Dallas, TX

Dallas companies run on Microsoft 365, cloud business applications and office networks that have to ride out grid emergencies and spring storms. NetSys is an IT company that manages all of it for firms from Uptown and the Arts District to Las Colinas and Legacy: the help desk, security, backups, vendors and compliance records, delivered remotely from our office in Brooklyn.

The short answer

NetSys is a managed IT and cybersecurity company serving Dallas organizations remotely: an engineer-staffed help desk, device and Microsoft 365 management, ThreatDown managed detection and response, firewall and Wi-Fi management, backups with restore tests, vendor management and IT consulting. Dallas is far outside our on-site area, so NetSys does not send engineers to Dallas offices; laptops arrive pre-configured through Windows Autopilot, and your staff or cabling contractor handles anything physical. The help desk answers from 3 a.m. to 10 p.m. Central every day, monitoring runs 24/7, and pricing is per user per month after an assessment, on month-to-month terms.

What an IT company handles for a Dallas business

Dallas is a headquarters town. Fortune's 2026 list put 24 Fortune 500 companies in the region and 11 of them in the city itself, and around those headquarters sits a deep layer of smaller firms: accountants, law firms, lenders, design studios, medical groups and distributors that have real security obligations and nobody whose full-time job is IT. For them, one IT company should own the whole picture under one agreement: the help desk, laptops and phones, Microsoft 365 accounts and licensing, email filtering, ThreatDown on every device, Keeper for shared passwords, backups with tested restores, the firewall and Wi-Fi, and the calls to the internet provider, the copier company and the software vendors. A company with an internal IT lead can hand us part of the job instead, such as security monitoring, a cloud migration or after-hours patching, and keep the rest. Either way there is a dedicated account manager with a real cell number and a written list of what we look after.

How remote onboarding and support work from Brooklyn

Dallas sits roughly 1,370 miles from our office, so the model is remote and we say so before anything is signed: NetSys does not send engineers on site anywhere in North Texas. Onboarding takes about four weeks. In week one the NinjaOne agent goes onto every computer and the environment is documented in IT Glue. In week two we review the Microsoft 365 tenant for stale accounts, missing multifactor authentication, risky sharing links and mail rules that forward outside the company. In weeks three and four devices enroll in Intune, ThreatDown, Barracuda and Keeper go in, and replacement laptops are drop-shipped to the office or to employees' homes, ready for first sign-in. A new firewall or access point arrives configured; your office manager or cabling contractor mounts it while our engineer stays on the phone. From then on, staff call, email or message the help desk, and anything severe goes straight to your dedicated engineer.

Industries we serve in Dallas and the systems they run

The Federal Reserve Bank of Dallas counted financial activities at 10.1 percent of Dallas employment in mid-2026, a larger share than New York City's, and the city now hosts NYSE Texas and the Texas Stock Exchange, which began live trading on July 10, 2026. That sets the tone for due-diligence questionnaires and SEC examinations. The Southwestern Medical District employs about 43,000 people across UT Southwestern, Parkland and Children's Health, and a wide ring of physician groups and dental offices surrounds it. Southern Dallas County's inland port and the Alliance hub in Fort Worth anchor distributors and 3PLs, and DFW has more manufacturing employment than any other Texas metro. Each group runs its own core system, which we describe generically: tax and practice-management software, a document management system, an EHR and billing platform, imaging software, a warehouse management system, an ERP. We support the identity, devices, network and backups underneath and work with the vendor when the application itself fails.

Office towers, suburban campuses and the circuits behind them

Where the office sits changes the IT plan. Kidder Mathews put Dallas CBD direct vacancy at 32.2 percent in the second quarter of 2026, while Uptown and Turtle Creek carried the market's largest construction pipeline, including Goldman Sachs's 800,000-square-foot campus and Bank of America Tower at Parkside, so many firms are weighing a move into a newer building. A move is an IT project: circuits ordered months ahead, a network designed before the low-voltage contractor arrives, and phones, printers and Wi-Fi working on the first morning. Towers downtown, in Uptown and in Las Colinas usually offer several carriers, while suburban office parks in Richardson, Plano and Frisco sometimes have only one. Options to check at your address include AT&T Business Fiber, Spectrum Business and the former Frontier fiber network, which Verizon took over in January 2026. We design for two paths into every office, with a cellular backup line on the firewall when the building cannot offer a second wired carrier.

Grid failures, tornadoes and the Dallas ransomware year

North Texas gives a continuity plan plenty to work with. During Winter Storm Uri in February 2021, rolling blackouts that Oncor first described as 15 to 45 minutes long left parts of Dallas and Tarrant counties without power for more than a day. On October 20, 2019 an EF3 tornado with 140 mph winds cut a 15.76-mile path from Irving toward Richardson, and on May 28, 2024 straight-line winds knocked out power to hundreds of thousands of Oncor customers and led to a federal disaster declaration that came to include Dallas County. Then there is the city's own experience: attackers using the Royal ransomware spent about a month inside City of Dallas systems in spring 2023, took roughly 1.2 terabytes of data and began encrypting on May 3, and Dallas County was hit by the Play group that October. Our design response is data in Microsoft 365 and Azure with independent backups held outside Texas, laptops as the real workplace, UPS units sized for a clean shutdown, and a written plan for a building with no power.

Texas data-security law in plain terms

Texas Business and Commerce Code section 521.052 requires a business holding sensitive personal information to keep reasonable procedures protecting it and to destroy records it will no longer retain. Section 521.053 sets the notice clock: affected people within 60 days after the business determines a breach occurred, and, since a 2023 amendment took effect on September 1 that year, the Attorney General within 30 days whenever at least 250 Texas residents are involved. The Texas Data Privacy and Security Act has applied since July 1, 2024, although businesses that are small under federal SBA standards are largely exempt. Senate Bill 2610, in force since September 1, 2025, lets a Texas business with fewer than 250 employees defend against exemplary damages after a breach if it maintained a cybersecurity program conforming to a recognized framework such as the NIST Cybersecurity Framework or the CIS Controls. Medical and dental practices also answer to Health and Safety Code chapter 181. This is general information, not legal advice.

From our published case studies

Complete Managed IT, Cybersecurity and Help Desk for a 20-Seat Organization

A 20-seat organization handed NetSys the whole of its IT: managed services, the cybersecurity stack, a help desk its people use, onboarding for every new hire and phishing training for everyone.

The published case study shows a 20-seat organization that handed NetSys its managed IT, security stack, help desk, new-hire onboarding and phishing training under one agreement, the scope most Dallas firms of that size ask about. It is not a Dallas engagement.

Common Questions

Dallas, TX FAQs

Who provides IT services in Dallas?

Dallas businesses can hire a local IT shop with technicians across the Metroplex or a remote managed service provider. NetSys is the second kind: a managed IT and cybersecurity firm founded in 1998, with one office, in Brooklyn, that supports Dallas organizations remotely. One month-to-month agreement covers the help desk, devices, Microsoft 365, security, backups, the office network and your technology vendors. If your work regularly needs a technician standing in the office, tell us at the start, because we do not send engineers to Dallas.

How does IT support work for Dallas organizations?

Staff reach an engineer by phone, email or Teams from 3 a.m. to 10 p.m. Central, seven days a week, and monitoring and emergency response run 24/7. Computers are managed through NinjaOne and Intune, accounts through Microsoft Entra ID, and the firewall and access points through their cloud consoles, so nearly every fix happens remotely. Replacement hardware ships pre-configured. Physical tasks, such as moving a desk phone or mounting an access point, are done by your staff or your own cabling contractor while our engineer guides them.

How much do IT services cost for a Dallas company?

Managed IT and IT support are priced per user per month after an assessment, and we do not publish a rate card. The figure for a Dallas firm moves with headcount, the number of devices each person uses, whether you still run servers or only cloud services, the security tools included, and the compliance work your clients, auditors or insurer require. Projects such as an office move or a Microsoft 365 tenant migration are quoted separately after scoping. Every agreement runs month to month, so the service has to keep earning its fee.

Is NetSys a Dallas company?

No. Our only office is at 1 Prospect Park SW, Suite 6E, Brooklyn, NY 11215, and the main line is 845-203-3914. Dallas is one hour behind Brooklyn, which works in your favor: our engineers start before most North Texas offices open, so overnight patching is finished early and the help desk is already answering when your first employee logs on. What we cannot offer is a person in your building. That is why the service relies on cloud management, drop-shipped equipment and your own staff or contractors for anything physical.

How fast do you respond when something breaks?

Our written commitments for critical issues are a ten-minute phone response and a thirty-minute remote response; standard issues get a thirty-minute phone response and a one-hour remote response. Severe problems such as ransomware, a dead internet circuit or a mail outage skip the queue and go to your dedicated engineer, and monitoring and emergency service stay on overnight. Over the last three years we have handled more than 30 ransomware incidents, and every one was fully recovered; clients with a disaster recovery plan in place were back within 24 hours.

Which Dallas-area cities do you support?

All of them, the same way: remotely. That includes Downtown, Uptown, the Design District and North Dallas, Las Colinas and Irving, Addison, Richardson, Plano, Frisco, Garland, Grand Prairie and the southern Dallas County cities around the inland port. Fort Worth, Arlington and Plano have their own managed IT pages, and our Texas page covers the rest of the state, including Houston and Austin. Because nothing depends on travel, a company with offices in Dallas and Houston, or Dallas and New York, gets one help desk and one set of policies.

Which compliance rules do you help Dallas firms meet?

The ones your industry brings with it: the HIPAA Security Rule and Texas Health and Safety Code chapter 181 for medical and dental practices, the FTC Safeguards Rule and IRS Publication 4557 for tax preparers, SEC Regulation S-P for advisers and broker-dealers, the Texas Disciplinary Rules of Professional Conduct for law firms, and DFARS 252.204-7012 with NIST SP 800-171 for defense suppliers. We put the technical controls in place, keep the evidence and draft the policies; your attorney decides which rules apply.

Can you test our security before we sign anything?

Yes. The one free service we offer is an external penetration test: a remote test of your internet-facing systems, such as the firewall, VPN and any exposed servers, within a scope we agree in writing first. For a Dallas firm it is a practical way to see how our engineers work and what an attacker would find from outside. It does not cover internal systems or a full review of your environment; those come with onboarding or a separately quoted project.
